lMPROVEMET IN GAS APPARATUS.

The Schedule referred to in these Letters Patent and making part ofthesme;

To all vwhom it may concern.-l

Be it known that I, ABRAHAM L. BOGART, of

the State ot' New York, have invented certain new and usefulImprovements in Gas Apparatus; anddo hereby declare that the followingis a. full, clear, and exact description thereof, refrence being had tothe accompanying drawing making a part ot' this specification, inwhieh-' Figure l is a side elevation of luy apparatus while inoperation; A

lfigure 2 is a central longitudinal section of the saine; and

lfjgurc 3 is a like view of a retort for combining oxygen l'rom the airwith ordinary coal gas.

Letters ot'like name and kind refer to like parts in cach otthe figures.

My invention has for its object thc conversion of hydrocarbon liquidsinto a Iixcd gas for heating, cooking, and illuminating purposes; and

.lt consists, principally, in the peculiar construction of tlleretort,and of its adaptation to and combination with the burner, substantiallyas ishercinafte'r shown.

lt also consists in the construction of' the reservoir for containingalcohol for use in heating the retort, and in the adaptationof'saidfrcservoir to the burner, and its combination with the retort,substantially as is hereinafter set forth.

It i'nrthe' consists in the combined burner, retort, and alcoholreservoir, coiistrnctcd and arranged substantially as and ior thepurposehereinafterspecified.

.lt finally consists in thelpeculiar construction of the illuminatingburner, by means ot which it is adapted to the nseof the gas generatedby the machine, as is hereinafter shown.

A represents an annular metal ring, having secured to and projectingdownward. from its inner edge a short cylindrical iange, c, providedupon its inner surface with a female screw-thread, while from the outeredge'ot'snid disk projects, upward a second flange, a', within which isplaced ai cylinder of reticJul-ated shcct lnctal B, having a hcigbtequal to about-twice thatoi' said flange, and a dian eter somewhat lessthan the space between its walls.

Resting upon the upper cud 0f` the cylinder B is a cap, C, convex uponits ripper` side, and provided upon its outer edge with a flange,c,'which projects downward and slightly outward, (as shown in tig. 2.) Aboss, c', projecting downward from the center of said cap,A contains oneend of a rod, 1), thc opposite cud oi' which passes downward into a.cross-bar, E, spanning'the opening inthe disk A, and serves to bind saidcap, disk, andthe cylinder B rmly together.

Secured within, and projecting vertically downward from the cylindricalflange a, is ashort pipe, F, thc

lower end' ot' which is reduced in size about one-half,

followiug-dt'zscribed incassare employedfor vaporizing hydrocarbonoils:`

Secured 'uponr the outcredgc of the cap C, and forming part ofthe same,is a circular chamber, G, which entirely surrounds said cap, and isprovided upon opposite sides with suta-blcsockets for the reception ofthe threaded ends of'two pipes, the first of which, H,' communicateswith the reservoir for containing oil, while the second pipe, l,extending outward, down- 'ward, and inward, terminates iu aver-ticalbranch, K immediately beneath the center ofthe burner, the upi per endof` said branch l being provided with a smalb opening, x, f'or thepassage of gas, while its lower end is inciosed by means olf ascrew-cap, k.

An' annular cup, L,- surrounds and forms a part of` the flange c of thebaseo t' the burner, anda similar cup, M, is placed immediately beneaththe vertical portion of the pipe I. A packing of asbestos andwire-gauze, h, being placed within the pipe H, between the burner andthereservoir, the device is ready for operation as follows:

. The cups L and M being filled with alcohol, the latter is ignited,and, burning upward against the pipe I and thc chamber G, beats themrapidly, so'that, by the time that the contents ofthe cup M is burn'edout, oil may be admitted from the reservoir, The oil, passing throughsaid chamber G and pipe I, becomes vaporized, and, upon issuing from theburner, is ignited by thc burning alcohol within the cup L.

In from three to tive minutes thc chamber or retort yGr attains a.cherry-red heat, after which the oil passing through, 'is converted intoa-fixed gas, suitable -for either heating orilluminatiu purposes.`

As the gas formed by this met lod is too rich for use in an illuminatingburnerv that will pass over two feet per hour, it becomes necesary'to employ the following-described construction A short nipple, O, having inand through its np per end a small aperture, c, and provided upon itscxterior surface with a male screw-thread, is secured upon a. pipe,P,leadiug from the retort. An ordinary pipe F should be placed at ashort distance above the brauch K, so that air may enter freely withinsaid pipe. In order that the'pipo F 'may be secured in' such position,two lugs, W, are attached to the branch K,

and, projectingupwardl upon` opposite sides of said pipe, are securedthereto by means of wire passing through suitable openings within saidlugs and around said pipe.

For heat-ing purposes, whcreordinary coal-gasis used, I have i'onndgreatadvantage toresult from thc employment ofthe retort and burner shown iniig. 3, in which said gas is admitted through the pipe S into the openendv of the vertical pipe T, unites with an inward-Howing current ofair, and passes into and through the retort G, where thc chemicalcombination between said gas and air is perfected.

Upon leaving the retort, the oxygeniz'ed gas passes down into thechamber U, beneath the burner, and upward through one 0imore reticulateddiaphragms u, into and througlll said burner, having acquired, by

1. The retort G, constructed as described, and com binedwith the heatingburner, substantially as and for the lpurpose specified.

2. The annular cup or alcohol reservoir L, coru-V bined with the retortG and with the heating bur-der, in thc-manner and for the purposesubstantially as dcscribed.

3. The combined burner, retort, arid alcohol reservoir, when constructedand arranged substantially as shown aud for the purpose sct forth.

4. `'.lhe illuminating burner, composed of the perforated nipple 0 andthe burner R, provided with the slot r, substantially as and for thepurpose shown.

5. In combination with ,the gas-jetz and pipo or mixing-chamber F, thcair-passages f and f', substantiallyas and for the purpose set forth.

In testimony v'that I claim thc foregoing I have hereunto set my handthis 17th day of December, 1870.
